Understanding Genetic Variants and their Impact on Proteins and Phenotypes

The video explains how DNA codes for proteins and the role of genetic variants, also known as mutations, in altering DNA sequences. It discusses the impact of these variants on coding and non-coding DNA, affecting protein structure and function. Genetic variants can lead to changes in phenotype by altering amino acid sequences or influencing RNA polymerase binding, thus affecting protein production.

What is the role of DNA in coding for proteins?

How does a genetic variant affect the sequence of DNA bases?

Explain the difference between coding DNA and non-coding DNA.

What are the potential effects of a genetic variant in coding DNA?

What is meant by the term 'phenotype' in the context of genetic variants?

What is the function of RNA polymerase in relation to non-coding DNA?

How can a genetic variant in non-coding DNA influence protein production?
